sGroup is undefined when mDataProp is ised as a data source

[GoogleCodeExporter]

1. Use version 1.1.2 of row grouping with version 1.8.2 of datatables
2. Call rowGrouping() on oTable.

You'll see an error that says: 
sGroup is undefined - line 122

Not sure if this is because I'm passing the data in using aoColumns and aodata.

To fix you need to change line 286 from:
sGroupData = 
oSettings.aoData[oSettings.aiDisplay[iDisplayIndex]]._aData[properties.iGrouping
ColumnIndex];

to:
sGroupData = 
oSettings.aoData[oSettings.aiDisplay[iDisplayIndex]]._aData[oSettings.aoColumns[
properties.iGroupingColumnIndex].mDataProp];                    

Basically sGroupData gets undefined set to it (which carries through to line 
122) because _aData isn't an array or indexable... it's an object with the 
mDataProp values as keys.

This also should be done for second level of grouoping.

This code will not work for more complex mDataProp e.g. "mDataProp": 
"innerBean.name"

My solution for more complex mDataProp (e.g. "mDataProp": "innerBean.name") is 
like this:
var tmp1 = oSettings.aoData[oSettings.aiDisplay[iDisplayIndex]];
var tmp2 = oSettings.aoColumns[properties.iGroupingColumnIndex].mDataProp;
sGroupData = eval("tmp1._aData." + tmp2);

Hi,

This is fixed in the latest version of plugin. Could you please take a look at 
the 
http://jquery-datatables-row-grouping.googlecode.com/svn/trunk/serverSideJSONP-o
bjects.html where I have used server side processing with object data source 
and it works now. Here is used JSONP call because server-side processing page 
is on Allans datatables site, and I do not have php hosting on google code. 

I have used solution similar to one that serbiaunite has proposed:

sGroupData = 
oSettings.aoData[oSettings.aiDisplay[iDisplayIndex]]._aData[properties.iGrouping
ColumnIndex];
if (sGroupData == undefined)
       sGroupData = oSettings.aoData[oSettings.aiDisplay[iDisplayIndex]]._aData[oSettings.aoColumns[properties.iGroupingColumnIndex].mDataProp ]; 

It seems to me that it works on the demo site. Let me know whether it works in 
your example.

serbaiunite hvala na pomoci, drago mi je da uspesno koristis ovaj plugin.

Jovan

Hi,

I tested this fix but it doesn't work in my case. It is the problem I
described in one of my comments on this bug. I have scenario where
sGroupData2 comes from complex source. My DT definition has this part:
"aoColumns" : [
   {....
   { "mDataProp": "innerBean.name" },
    ...
and this value I want to display in second level of grouping. So I used
this solution that also works in simple cases:
if (sGroupData2 == undefined){
   tmp1 = oSettings.aoData[oSettings.aiDisplay[iDisplayIndex]];
   tmp2 = oSettings.aoColumns[properties.iGroupingColumnIndex2].mDataProp;
   sGroupData2 = eval("tmp1._aData." + tmp2);
}

Thanks for the useful plugin!

I am sorry but none of these solutions work when mDataProp is a function. Any 
suggestions?

Thank you.
